Switching converter with auxiliary driver

Abstract

An apparatus includes a first transistor, a second transistor, a third transistor, a fourth transistor, an inductor, and a current injection circuit. The first transistor is coupled between a power terminal and a first switching terminal. The first transistor has a first control terminal. The second transistor is coupled between the first switching terminal and a reference terminal. The second transistor has a second control terminal. The third transistor is coupled between the power terminal and a second switching terminal. The third transistor has a third control terminal. The fourth transistor is coupled between the second switching terminal and the reference terminal. The fourth transistor has a fourth control terminal. The inductor is coupled between the first and second switching terminals. The current injection circuit is coupled to the first switching terminal.
